Study of INCA035784 for certain blood cancers
This trial tests a new drug, INCA035784, for people with myeloproliferative neoplasms (MPNs), a group of blood cancers. It may help if your MPN is called myelofibrosis (MF) or essential thrombocythemia (ET) and has a specific genetic change (CALR mutation), and you've already tried other treatments.
Palo Alto, CaliforniaAges 18 years+ - NCT03779854RecruitingPhase 2
Preventing graft-versus-host disease in kids after stem cell transplant
This trial tests whether removing certain immune cells (T cells) from the donor transplant can lower the risk of chronic graft-versus-host disease (long-term immune attack after transplant) in children and young adults with blood cancers. If you qualify, it may help improve transplant outcomes while tracking safety and side effects.
Los Angeles, CaliforniaAges 6 months–26 years - NCT03113643RecruitingPhase 1
SL-401 with standard drugs for hard-to-treat blood cancers
This Phase 1 study tests SL-401, given with azacitidine and sometimes venetoclax, to treat acute myeloid leukemia (AML), high-risk myelodysplastic syndrome (MDS), or blastic plasmacytoid dendritic cell neoplasm (BPDCN). It aims to find a safe dose and see whether the combination can improve blood cancer control.
Duarte, CaliforniaAges 18 years+ - NCT03207854Recruiting

This study looks at continuing niraparib for a longer time in people who already finished an earlier niraparib trial and are still benefiting. It may help understand how safe and useful long-term treatment is for you.
Encinitas, CaliforniaAges 18 years+ - NCT04794322Recruiting
Testing uterine fluid to help detect ovarian cancer
This study checks whether a sample of fluid from the uterus (uterine lavage) can help detect ovarian or fallopian tube cancer. You may join if you are having certain gynecologic surgeries or, in a smaller group, you have a BRCA1/2 mutation.

What taking part in a neoplasms study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
Neoplasms trials in other states
Common questions
- Are there neoplasms clinical trials in California?
- Yes. We're currently tracking 248 recruiting neoplasms studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a neoplasms study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a neoplasms trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New neoplasms studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
